Proposed Group: Agentic Integrity Verification Specification Community Group
The Agentic Integrity Verification Specification Community Group has been proposed by Ben Stone:
AI agents increasingly perform consequential actions on behalf of humans —browsing websites, submitting forms, executing code, and making purchasing decisions. When things go wrong (an agent takes an unintended action, produces an incorrect output, or is used in a regulated context), there is currently no agreed upon way to prove what the agent actually did, in what sequence, and whether the record has been tampered with. Existing observability tools (such as OpenTelemetry and LangSmith) log agent behavior but provide no cryptographic guarantees of completeness or authenticity.
Regulatory frameworks are beginning to require audit trails for AI systems (EU AI Act Article 19, ISO/IEC 42001, NIST AI RMF), but none prescribe a format. This group will explore open formats for cryptographic proof of AI agent sessions —portable, self-verifiable records that any party can verify independently, without network access or external infrastructure.
The Agentic Integrity Verification Specification (AIVS) v1.0 is intended to serve as a starting point for discussion within the group, but is not intended to constrain the group’s discussions or decisions about future deliverables.
You are invited to support the creation of this group. Once the group has a total of 5 supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account.
Once launched, the group will no longer be listed as “proposed”; it will be in the list of current groups.
If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on site-comments@w3.org
Thank you,
